IMPROVEMENT IN STUMP-EXTRACTORS.

Speciication forming part of Letters Patent No. 33,883, dated December 10, 1861.

.To all whom it may concern:

Be it known that we, CHARLES J. GLENN, CORTLAND BALL, and URIAH S. HACKETT, ot Unadilla, in the county ot' Livingston and 4 State of Michigan, have invented certain new and useful Improvements in Stump Machines; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, and to the letters of reference marked thereon.

In the annexed drawing, making part of this specification, A represents a frame provided wi th an axle upon which are two wheels B.

G is a lever which has its fulcrum on the frame over the axle. The long end of this lever extends forward and is connected by a cord E to the short end of a lever D, the oord E passing through a pulley-block G, asis shown in the drawing. Thelever Dhas its fulcrum in the frame A at A cord F attaches to the forward and long end ot lever D and passes around two pulleys ct a in the frame. Then power is applied to the cord F, the lever D operates upon lever C through cord E and draws it down. A chain or other convenient attachment connects the short arm of lever O with the stump at the rear of the machine, and when the front end of lever C is drawn down great power is applied to the stump. The lever C can be raised and the chain tightened, so that the stump may be moved by degrees until it is removed from the earth.

d isha support for the forward end ot' the frame.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

The employment of the levers C and D, the cords E and F, thel block G, and the pulleys a d ct, constructed and arranged for extract` ing grubs and stumps, substantially as herein specified. 0
